The Next Big Phones Could Bring a Billion People Online

Posted by in categories: internet, mobile phones, neuroscience

Nowhere is that clearer than in Africa, which has the world’s lowest share of people using the internet, under 25%. The cohort of 800 million offline people spread across the continent’s 54 countries is younger and growing faster than most, but incomes are lower and a larger share of residents live in rural areas that are tough to wire for internet access—or, for that matter, electricity. Now, however, a handful of phone purveyors are trying in greater earnest to nudge internet-ready upgrades into African markets, with models designed with an eye toward rural priorities (first those of rural India, where they’re already hits), rather than battered thirdhand flip phones from the heyday of the Spice Girls.


About half of humanity don’t have internet access, and a lot of those people are in Africa. Enter a $20 device with smartphone brains and a five-day battery.

How Peter Shor’s Algorithm is Destined to Put an End to Modern Encryption

Posted by in categories: computing, encryption, information science, internet, quantum physics

RSA Encryption is an essential safeguard for our online communications. It was also destined to fail even before the Internet made RSA necessary, thanks the work of Peter Shor, whose algorithm in 1994 proved quantum computers could actually be used to solve problems classical computers could not.

The Privacy Project

Posted by in categories: biotech/medical, business, internet

Companies and governments are gaining new powers to follow people across the internet and around the world, and even to peer into their genomes. The benefits of such advances have been apparent for years; the costs — in anonymity, even autonomy — are now becoming clearer. The boundaries of privacy are in dispute, and its future is in doubt. Citizens, politicians and business leaders are asking if societies are making the wisest tradeoffs. The Times is embarking on this monthslong project to explore the technology and where it’s taking us, and to convene debate about how it can best help realize human potential.


The New York Times is launching an ongoing examination of privacy. We’ll dig into the ideas, history and future of how our information navigates the digital ecosystem and what’s at stake.

Why Quantum Computing Requires Quantum Cryptography

Posted by in categories: computing, encryption, internet, quantum physics

Quantum computing is cool, but you know what would be extra awesome — a quantum internet. In fact if we want the first we’ll need the latter. And the first step to the quantum internet is quantum cryptography.

In new space race, companies jostle for $1 trillion market

Posted by in categories: Elon Musk, humor, internet, space travel

“We joke that ‘The Martian’ would have been a much more boring movie,” said Justin Kugler, a vice president at Made In Space.

Fifty years after the first men walked on the moon, a new space race is underway, this one for a piece of what Wall Street analysts say could become a $1 trillion global space market. Around the world, companies such as Made In Space are launching — often literally — new products and services, building satellites to provide broadband internet, spaceships to take tourists on zero-gravity rendezvous, and mining equipment to extract minerals from asteroids.

On HoustonChronicle.com: Elon Musk injects ‘X’ factor into space quest with bold vision, mixed track record.

Defense against wireless attacks using a deep neural network and game theory

Posted by in categories: business, habitats, internet, mobile phones, robotics/AI, security

A growing number of devices are now connected to the internet and are capable of collecting, sending and receiving data. This interconnection between devices, referred to as the Internet of Things (IoT), poses serious security threats, as cyberattackers can now target computers and smartphones, but also a vast array of other devices, such as tablets, smart watches, smart home systems, transportation systems and so on.

For the time being, examples of large-scale IoT implementations (e.g. connected infrastructure, cities, etc.) are somewhat limited, yet they could soon become widespread, posing significant risks for businesses and public services that heavily rely on the internet in their daily operations. To mitigate these risks, researchers have been trying to develop to protect devices connected to the internet from wireless attacks.

To this end, two researchers at Baoji University of Arts and Sciences, in China, have recently developed a new method to defend devices in an IOT environment from wireless network attacks. Their approach, presented in a paper published in Springer’s International Journal of Wireless Information Networks, combines a with a model based on , a branch of mathematics that proposes strategies for dealing with situations that entail competition between different parties.
